My best guess is that sprinting is a form of interval training. Especially in high intensities, interval training has been numerously shown to be highly effective as opposed to regular/endurance training (long distance or longer period of time) in various aspects, including the androgenic response it provokes.

Endurance training has also long been touted to be the best strategy for fat loss for example but interval training has been shown to achieve even better results, without the stressfulness of prolonged training (think cortisol and such).

I always go for HIIT whenever my time is limited a long gym visit and it always hits me how efficacious it is. I have also experienced the appetite suppression you've described but only immediately after the activity. It subsides after about 2 hours after which I get very hungry.

Charles is a clinician, sometimes he sees things in his training practice that only many years later get confirmed by lab study. That doesnt give him a license to print bull**** pseudoscience, but also not reason to immediately write him off (although one of his biggest accomplishments is bringing high-dose fish oil to the fitness industry... LOL)

However I find it hard to eat, even repulsive right now. I don't know if the increased insulin sensitivity means my cells are actually using what I eat. But water weight is down, so is edema.

Anyone know whats going on?

Jon Gabriel, behind the Gabriel Method, says that the best exercise for weight loss is maximal intensity, to the point of "picturing a tiger chasing you". He says the best way to tell your body that its OK to drop weight is to trick it into thinking it must be lean to survive. In the past Ive also lost all appetite doing max effort work. Theres just something about MAXIMAL effort that is so effective for fat loss, probably hormonal.

Based on your posts, you seem to be on a similar journey to me. You should try other max effort or explosive type work, like power cleans, DB snatches, and clap pushups - other exercises where you can give maximum intensity, without exceedingly heavy weight (like the difference between sprinting vs. squatting). I feel like theres unique fat burning/hormonal benefits from this type of high intensity but low resistance type of exercise.

I completely agree with you. Sprinting literally is telling the body to drop all excess weight and put on lean mass where it needs it. I have incorporated Power cleans.

The androgenic response must be intense since I being noticeably more masculine. Water Weight is dropping, becoming bold, and bottom abs are strarting to appear, Neck is growing substantly

Body must be adapting thinking your either the top hunter in the tribe, or you are running for your genetic survival. Quote from his sites. " Long, slow workouts can lead to overtraining stress, and even food cravings; but exercise done right is brief, intense, playful, bendy, and includes plenty of rest. Best of all, it changes your biochemistry so you burn fat all day long."

"It Increases Leptin Sensitivity. Leptin is the hormonal messenger that links your fat cells to your brain and tells your body to “eat more” or “that’s enough.” When you’re overweight, your brain often loses its sensitivity to leptin, so it’s saying “enough already!” but your brain doesn’t hear it because it’s been bombarded for so long. So you continue to crave food and eat more than you should.

Intense exercise makes you very sensitive to leptin, so you’ll feel full more quickly, and you simply eat less without trying."

Another thing to consider, regarding leaning out and health in general: giving blood. Ray has talked at length about the dangers of iron overload; that historically, arsenic was prescribed for anemia whereas now iron is; women age more slowly than men until menopause, then age at an equivalent pace; in the nations where iron is added to grains, obesity and diabetes are high. The only way for men to actively lower their iron stores is through blood letting, AND it could save a life. Win/wins all day. Previous raypeat forum member Natedawwgh was really adamant that his own health took a drastic turn for the better after he "depleted" his excess iron.

OP may be past the risk at this stage, but for other readers, think about warming up. I damaged achilles tendons trying short sprints a while ago, and I know I'm pretty sure I'm not the only one to do so. They take a long time to heal.

Yeah take the good with the bad. He has proven to be a successful coach. He has also popularised the eccentric training which Peat's view is that its stressful and concentric movements are favourable.

I'm paraphrasing Ray Peat here: Push the bike up the hill, ride it down. Which is an example of focusing on concentric movement, avoiding eccentric. Perhaps thats why he says sprinting is probably ok but there are more favourable activities in his opinion which when answering the question didn't elaborate on. Someone needs to clarify with Ray Peat about exercise and see if he goes more in depth about his views.
